Abstract

Flemish percussion boxes characterized in that it consists of a set consisting of two resonance boxes, preferably wooden, prismatic in shape, with a hollow body consisting of a treble box (Fig. 1.1) and a bass box (Fig. 1.2) . Both boxes are laterally attached to a separator (Fig. 1.3). They are of equal height. They contain on the upper face or base, the resonance cover with a square shape (Fig. 1.4) and on the lower face or base, preferably, are the acoustic outlet holes (Fig. 1.5).

Description

Flamenco percussion boxes.

Technical sector

This new model fruit of the invention is included within the percussion musical instruments.

State of the art

There is currently a wide variety of percussion instruments created to reproduce certain Sounds with which to make music. Many of them are born from the need to cover a certain frequency range (serious, treble), such as bongos, to play alone or to Accompany, for example, congas. Both instruments share similar characteristics, such as the use of wood and leather for its manufacture, but each one provides a different range of frequency so they complement each other perfectly.

The flamenco cajón as well as others percussion instruments of different geometric shapes, have a very particular sound thanks to the combination of woods and metals such as guitar strings - curbs, bells, etc., but they consist of a single soundboard which Limit your frequency range.

Although we also find instruments of percussion formed by a set of two soundboard as be the bongos or the Perfected Musical Instrument (Clasif. Main: G10D13 / 00, Application number: U200401280), none of these incorporate vibratory metal elements as if they do Flamenco Percussion Boxes.

Object of the invention

According to the invention, a musical instrument consisting of two wooden boxes of form prismatic and of different sizes, collaterally joined together, in which a percussion system consisting of metal rods attached to the face - side or upper base of each box.

Flamenco Percussion Boxes are the result of inventive by combining on the one hand the acoustics and the loudness of the flamenco cajón and on the other hand, the aesthetics of the bongos and the Perfected Musical Instrument, in order to create a own instrument for flamenco, bringing new sounds that serve as an accompaniment to the traditional drawer as well as for your solo execution.

Detailed description of the invention

To get a sound that complements with that of the Flamenco Cajón I invented a system that uses rods metal attached to thin square wooden planks, vibratory and practicable that will be the covers of the boxes of resonance.

Flamenco percussion boxes (1) are a set of two wooden resonance boxes joined, of equal height but square bases of different sizes, where upper bases are the Resonance Caps (1.4).

These "Tapas" are characteristic different from the rest of the box, they are thinner, they are slightly arched and have attached on the back or inner side, rods metallic preferably piano strings or guitar strings (2.2 and 3.2).

When you hit the top cover, it vibrates and so do the rods or piano strings that go in them attached, producing a typical and unique sound reminiscent of of the Flamenco Cajón. This vibration produced by the blow of hands and / or fingers can be adjusted by screws (1.6) that fix more or minus the arched lid to the soundboard.

Metal rods and piano strings do not they need to be tensioned unlike guitar strings, but if it is possible to replace them with thinner or thicker ones, controlling in this way the metallic bell characteristic of the wood and metal percussion. These rod may be subject to the lid in two ways:

1.- Through terminals similar to those used in electricity and these fixed to the top cover / inner face or back by screws and nuts (2.1).

2.- Through perforated metal angles, in L-shaped, glued to the top cover / inner face or back (3.1).

Both boxes, one for bass (1.2) and one for Treble (1.1) are joined by screws and nuts. And between them it goes a wooden separator (1.3).

In the face or bottom base of each box have practiced acoustic exit holes (1.5).

This new instrument gives the possibility of being executed with fingers and / or hands.

For its easy elaboration, since its manufacturing can be done entirely by hand but susceptible of industrial application, is that I claim.
